That is a good point.

In my case, I was trying to address the shortcomings of Apple Time Machine. I use a Mac mini as the server I work from on all my machines. Time Machine does the version Managment for me.

I just use Sync Thing through a VPN to keep an offsite backup of content files (not a complete OS restore) and to keep a copy of critical files on my laptop in case I am away from my home network and need to see a file.

I still need to implement a regular air gapped backup instead of the ad-hoc that I have now.
